Decision To Stay

May 1, 1985

OTTAWA — Canada will not withdraw from the United Nations Educational, Scientific and Cultural Organization. The United States, angered by money management and political attitudes, pulled out last year and Japan and Britain are considering doing so. Stephen Lewis, Canada's U.N. ambassador said there is mismanagement and ''a bureaucracy which is a little self-indulgent, some say grandiose even by U.N. standards,'' but Canada's government believes it is better to ''work like the devil from within'' to achieve reforms.
